All of Fernest is celebrating Olivia and the Seventh Legion's victory at the Battle of Ilys. Their festivities are cut short, however, when news arrives of a disastrous defeat on the northern front. Time is of the essence if they're going to save the remaining Legions before the empire strikes. The mission falls to Olivia, who sets off for the north with Claudia and Ashton in tow.

Lying in wait for them is the empire's General Rosenmarie, along with her Crimson Knights. Hungry for revenge after the death of her beloved General Osvannes, she'll stop at nothing to crush the Seventh Legion.

Can Olivia and the others stop Rosenmarie and her shadowy allies, or are they walking right into a trap?
